Dan Smith 3256eda85f Robustify Compute Node Hostnames backlog spec ... This is mostly a brain-dump spec on the topic of compute hosts and how fragile they are in terms of hostname handling. There has long been a requirement that computes can NEVER change hostnames, and we have few tools to even detect the problem before we corrupt the database if it happens. Here I have documented some of the things we could do to make that more robust, should we choose to do so. This is based on a recent near-catastrophe and thus reflects things that would have avoided pain in a real scenario. Per discussion at the PTG, I am adding this as a backlog spec, to be an overarching guide for multiple smaller specs to provide more detailed progress towards the goals described here.
